Abstract: 1,112,745. Vacuum switches; gas filled switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 27 July, 1966 [3 Dec., 1965], No. 51419/65. Heading H1N. In a circuit breaker having main contacts 5 in an evacuated envelope 17 shunted by a resistor 21 which is in series with an auxiliary switch 2, 8 the auxiliary switch is located within a chamber filled with compressed SF 6  which also surrounds the evacuated envelope 17. The circuit breaker is operated by a rod 7 coupled to a rotatable member 36 biased by a spring 1 against a cage 10 which acts through springs 3, 4 on the moving contact 19 of the vacuum switch. As rod 7 is drawn down member 36 is rotated away from cage 10 allowing spring 3 to open the contacts 5; subsequently member 36 strikes the moving contact 8 of the auxiliary switch thus interrupting the residual resistor current. The vacuum switch is located in an insulator 20 extending from a metal tank 122. This insulator also contains the resistor 21 which may be in the form of a granular material and may be non-linear. In a modification (Figs. 3, 4, not shown) the auxiliary switch is also located in an insulator (48) whose interior is connected to the chamber 122 only by a non- return valve (56). Several circuit breakers may be connected in series with voltage dividing capacitors (67) (Figs. 5-8, not shown).

A foil cover sheet 21, a transparent original 19, a copy sheet 20 and a sheet 22 are introduced in superposition between a rotating translucent glass cylinder 1 and a stationary polytetrafluoroethylene shield 3, the copy sheet being exposed by a light 2 and developed by an infrared heater 13 and by ammonia vapour which penetrates the shield through coverable holes 16, the sheets passing out of an exit 17. While the sheet 20 is being exposed it may be moistened by water vapour or an alkyl halide gas which penetrates the shield through perforations 15, the sheet 22 being vapour permeable and the sheet 21 being vapour impermeable so as to keep the surface of the cylinder dry. Thermostats 12 are provided to control the temperature of the liquids in storage chambers 9, 10. The sheets 21, 22 may form a sleeve enclosing the sheets 19, 20. The lamp 2 may be masked so as to expose the copy sheet after it has passed the perforations 15, enabling gas or vapour to be applied to a copy sheet before it is exposed. The apparatus can be used for development of copying material which has been exposed elsewhere, in which case the cylinder is made of opaque material.

A gyroscope WK disposed at or near the pitching axis M senses the pitching speed and an acceleration sensor BS is connected to an integrator to determine the linear vertical displacement speed of the body at the axis M. The control means 129 respond to the two outputs separately and in sequence to operate the locking devices 128 to reduce the amplitude of pitching and vertical oscillation. Fig. 4 shows a spring set having two gas springs 210, 211 which communicate with a hydraulic piston and cylinder assembly 203, 204 to act in series between body part 201 and track roller R, communication with one spring 210 being through a valve arrangement 216 comprising openable non-return valves which act in opposite directions and are individually controlled. In Fig. 5 (not shown) the valve arrangement is replaced by a lockable floating piston. In Fig. 6 (not shown) the track roller is carried by an arm attached to the centre of a rotatable link the ends of which are connected to pistons acting on a common body of hydraulic fluid communieating with a pair of gas springs. The gyroscope and acceleration sensor may be replaced by a pair of acceleration sensors spaced apart on opposite sides of the pitch axis M.

A second duct 8 is angled with respect to the duct 4 and has an outlet in the chamber directed generally towards the outlet of duct 4 and away from electrode 3 for carrying a second combustion flame during the use of the detector in the detection of hetero-compounds. A carrier 5 supports a salt 7 in the path of the second flame but not in the path of the first flame. The electrode 3 is frusto-conical and positioned in the chamber for collecting ions. To detect hetero-compounds, H is supplied to duct 8 and ignited at the outlet, so that the tip of the flame is in contact with a salt 7 appropriate to the compound being detected in the cup 6 of a salt-carrier 5. The sample is supplied to duet 4. Duct 8 is connected to a potential of - 200v. to - 300v, carrier 5 to earth or a positive potential and duct 4 to a potential of 0v. to + 300v. Carrier 5 is adjustable parallel to the axis of duct 8. To detect a hydrocarbon, the sample is mixed with combustion gas, supplied to duct 4 and burnt at the outlet. No gas is supplied to duct 8. Duct 4, duct 8 and the salt carrier 5 are all connected to a negative potential. In either case, ion current to electrode 3 increases in the presence of the compounds to be detected, and this current is amplified by an amplifier 12 and recorded by a recorder 13.

Abstract: 1,206,459. Colour television tubes. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 11 Dec., 1967, No. 56274/67. Heading H1D. A static convergence device for a three gun colour television receiver tube comprises two permanent magnets which are movable normal to the tube axis and which are also rotatable, these magnets co-operating with internal polepieces provided adjacent respective electron guns. In Fig. 7b the two magnets 10 and 11 are in the form of discs with poles o and x at opposite ends of a diameter, and have serrated edges so that they may be rotated easily about respective shafts 17 and 18 lying parallel to the axis of the tube. The shafts 17 and 18 are each mounted in a slot in a non- magnetic support member 19 and 20 so that the magnets can be moved towards or away from the tube. The three electron guns 9, 9<SP>1</SP> and 9<SP>11</SP> are separated by a magnetic shield 7 and are each associated with a pair of magnetic polepieces 8 energized by the permanent magnets. When the magnet 11 is rotated, electrons from the red and green guns 911 and 9<SP>1</SP> trace elliptical paths on the centre of the screen (Fig. 5, not shown), the size of the ellipses depending on the field strength, i.e. the distance of the magnet 11 from the tube wall. The magnet 11 is adjusted until the beams from the two guns meet at a central point, and the magnet 10 is then adjusted until the beam from the blue gun 9 impinges on the same point. Ferromagnetic plates 21 and 22 bridge the poles of the magnets to produce a shielding effect when the magnets are furthest from the tube. In an alternative construction, Fig. 8 (not shown), each magnet is in the form of a cylinder magnetized across a diameter and arranged in a casing adjacent a soft iron plate. Rotation of the magnet alters the direction of the field, and longitudinal displacement of the casing alters the intensity of the field.
